The number is 250 I believe and you start to lose context between nodes. Technology does allow that to scale, but it should be rotating in the best 250 for your local experience. That’s not how it works right now in any platform I’ve seen.

Those local experiences however are layered, so 250 can shift with context and meaning in the moment—That’s where this is getting fun with my zone architecture. When it can support memory between context shifts, I think 1500 may be appropriate scale, but it’s theory still.
